- Publication Series: Heyne Science Fiction & Fantasy Pub. Series Record # 716
-
Note:
- The series began with the publication numbered #3026, but there were 25 titles published before as 'normal' Heyne mass-market paperbacks. A few of them were later re-issued becoming part of this series, for example #3009 "Die nackte Sonne" by Isaac Asimov.
- The first publications in the series didn't necessarily state the publication series. However, Heyne did include them according to their own bibliographies, see this series.
- On publication dates: The month of publication of the second book of this publication series is explicitly given in the reader's forum of Moewig's Terra series: Books #3027 & #3028 were ''August 1964'' books. For the preceding books - #3026 in the new numbering and #299 and smaller numbers - giving the correct month is slightly imprecise: #216 is identified for March as per Terra # 276 with one SciFi book to follow every month, but then there would be a gap in June / July 1964 until the two aforementioned volumes kick in. It is most likely that books were always published towards the end of a month and that sometime in 1964 the ''official month of publication'' was set as the next full month.
- Because the number of published titles grew in a way that the numbering reached into the 5xxx (and higher) the catalogue numbers were later preceded by '06/'.
